# Small Conveyor Chains Technical Information

Calculation of Chain Stress
In general, at the outset, tentatively identify the chain dimension for being used referring to “Tentative determination of chain size”. Then, acquire “Theoretical chain stress (T)” (P213) for the tentatively determined chain, and multiply the value by “Speed coefficient (K)”, to get “Substantial chain stress (Ta)”. For safety, the considerable chain stress need to be lower compared to the “maximum allowable tension” stated inside the table of dimensions of respective chains. Consequently, the condition below needs to be happy.
Security ailment of chain stress
Significant chain tension (Ta) ＝Theoretical chain stress (T) ×Speed coefficient (K)
Substantial chain stress (Ta) ＜Maximum allowable tension
If this issue is not happy, pick a bigger chain by a single size and re-calculate.
Tentative determination of chain size
qDetermine the mass (weight) per unit length of components such as chain and attachment ωc (kg/m or kgf/m) assuming that it is actually ten percent in the mass (fat) with the conveyed object ω1 (kg/m or kgf/m).
wIn reference to the calculation formulas on, obtain “Theoretical chain tension (T)” (kN or kgf) and “Speed coefficient (K)”, and determine “Substantial chain tension (Ta)” (kN or kgf).
eIn reference to the table of dimensions of chains,determine the minimum chain, whose “maximum allowable tension” is higher than the “Substantial chain tension (Ta)”, and regard it as “tentatively decided chain”.
Value of speed coefficient (K)
The pace coefficient (K) expresses the severity of operation situation according to your traveling pace of chain since the issue gets severer as the traveling velocity of chain becomes increased.
Multiply “Theoretical chain stress (T)” by “Speed coefficient (K)” to get “Substantial chain tension (Ta)”.

When you design different conveyor methods working with little conveyor chains, the next primary ailments needs to be content.
a. Chain tension: The real tensile power in operation needs to be significantly decrease compared to the specified power from the chain.
b. Strength of loaded elements of chain: The real loads utilized to attachments, this kind of as rollers of base chain, leading rollers, side rollers, and so on. in operation has to be considerably smaller than the strength of these parts.
c. Wear life of chain: Lubrication conditions to make sure the put on lifestyle of chain should be fulfilled.
d. Sag adjustment of chain: The sag with the chain must be stored optimum by stress adjusters, take-up gadgets, guides, etc.
e. Some others: Suitable measures are taken to stop rail put on, machine vibration together with other issues.
The following complement the above.
